Abstract: The redistribution of nutrients in the cells seriously affected the commodity value and edible value of garlics cape. This paper studied the physiological mechanism that NO participates in the process of GA3 delaying garlics cape senescence via the cell inclusions transport,in order to provide experimental basis for the storage and refreshing of such kind of horticultural products. The basal part of garlic scape were treated with GA3,SNP,GA3+L-NAME,GA3+Na2WO4,GA3+HB or SNP+PP333 for three hours,respectively. Dried in the air and then stored at 4 ℃. Regularly measured diameter,water loss rate and level of endogenous NO in the garlic scape bulbet. The results showed that the increase of diameter and the loss of water in the garlic bulbet were inhibited by both GA3 and NO treatments. All treatments that eliminating NO or preventing any synthesis pathway of NO reduced the effect of GA3 in inhibiting the cell content redistribution in the garlicscape of Allium Sativum. It was concluded that NO might play a important role in the process of GA3 delaying material transfer in garlic scape.
